13 Claims. 1

This invention relates to new and useful improvements in applicators and dispensers.

One object of the invention is to provide an improved device for applying a liquid plastic material to medical gauze to produce strips for making casts and splints and dispensing such strips.

A particular object of the invention is to provide a portable and simple applicator and dispenser for cast and splint strips, which may be made relatively small, so as to be readily and expeditiously handled without waste or mess.

A further object of the invention is to provide an applicator and dispenser including an applicator container, in which the liquid plastic may be placed and a separate compartment, in which a roll of gauze may be mounted and a strip of gauze therefrom, drawn through the container for saturating and coating said gauze in a simple, sanitary and expeditious manner.

Another object of the invention is to provide a device of the character described wherein the strip of gauze passes through a guide removably mounted and extending through the plastic container, whereby said guide may be withdrawn for cleaning as well as for leading the strip of gauze therethrough.

Still another object of the invention is to provide a holder for a roll of gauze adapted to be detachably connected with the guide, together with means for controlling the feed of the strip of gauze to the guide.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following specifications and by reference to the accompanying drawings, wherein an example of the invention is shown, and wherein:

Figure l is a side view of an applicator and dispenser constructed in accordance with the invention, partly in elevation and partly in section,

Figure 2 is a horizontal sectional view of the same,

Figure 3 is a view taken along the line 33 of Fig. 1,

Figure 4 is a transverse sectional view taken on the line 4-4 of Figure 1,

Figure 5 is a detailed perspective view of the pressure regulator, and

Figure 6 is an enlarged sectional view of the dispensing end of the guide.

In the drawings, the numeral [0 designates a cylindrical container having a closure or plate I I at its rear end which may be made integral with the container or separate therefrom and suitably secured thereto. The forward end of the container is open and adapted to be closed by a truncated cap l2 having an annular flange it which is frictionally engaged around the open end of said container. The cap has a rectangular flat panel Hi provided with a slot l5 extending diametrically of the cap.

The end plate I l is provided with a diametrical slot l 6, alined longitudinally of the container with the slot l5. A wedge-shaped guide or support I! is inserted through the slot l6, pushed through the container and slot l5, so as to extend a short distance beyond the panel M at the front end of the container. Owing to the wedge shape of the guide it is frictionally held in the slots and may be removed rearwardly from the container. The guide is composed of two elongate members i3 and i9, which are channel shape in cross section, the lower member it being slightly greater in width than the upper member it, so as to receive the latter. The members Hi and 59 are provided with complementary holes 20, some of which may be larger than others, as is indicated in the drawings. When the container ill is filled with the liquid to a level above the guide H, such liquid will pass through the openings and saturate and coat the strip of gauze A extending through the guide. The guide is made Wide enough to permit free passage of the strip of gauze therethrough.

An elongate cylindrical bonnet or receptacle 2! is open at its forward end so that the rear end of the container it] may be inserted or telescoped thereinto. The bonnet is provided with stops 22 which limit the insertion of the container into the bonnet.

The lower member l8 of the guide ll has its rear end extended and bent downwardly to provide an inclined tongue 23; while the rear end of the upper member i9 is bent downwardly and rearwardly to form a transverse lip 2 overhanging the extended portion of the bottom member l8 and also forming a closure for the rear end of the guide.

A holder or magazine 25 for a roll of medical gauze is removably mounted in the bonnet. This holder is U-shaped in cross section and is made of light-weight spring metal so that its sides may be sprung apart for the insertion and removal of a transverse shaft 28. This shaft is provided with reduced trunnions 2'5 which engage in apertures 28 in the sides of the magazine. The flat bottom of the magazine is formed with a forwardly extending transverse extension 29, which is provided at each side with depending and inwardly bent clips 30, whereby a slip socket is formed for receiving the tongue 23 of the guide. In this manner the magazine is removably supported on the rear end of the guide and disposed at an inclination, whereby the shaft 26 is horizontally alined with the guide H.

A roll of medical gauze B is supported on the shaft soas to be unwound from the bottom, passed over the extension 29 and then between the lip 24 and the flat bottom of the member l8 to provide the strip A, which extends from the forward end of the guide and may be pulled'therethrough. A bracket plate 3! is fastened on the rear end of the guide member i9 so as to overhang the lip 24. A thumb screw 32 is screwed-threaded through this bracket and has a disk head 33 on its lower end bearing on said lip. The lip is made of resilient metal so that by adjusting the screw, pressure may be applied upon the strip of gauze passing under said lip and this pressure varied by'adj usting said screw.

'It will be noted that "the guide ll and the magazine are connected as a'unit by reason-of the engagement of the clips with the tongue 23. By removing the bonnet 21 from the container Ill, the magazine and the guide are made accessible and may be removed as a unit. For convienience in opening the. guide, the upright sides of the member l8 are provided-with indentations 34 at their rear "ends, which are engaged by dimples 35 in the depending sides of the member I9, whereby said members are detachably connected and may be separated to open the guide. It will be observed that the forward end of the upper guide member I9 is bent downwardly to form transverse flange 35 and then bent forwardly to form a transverse lip 31. By this arrangement the opening at the front 'end of the guide, through which the strip of gauze A is dispensed, is reduced in height and thus, the lip 37 co-acting with the .front edge of the lower member it provides a stripper, whereby the strip is pulled from the guide, surplus coating material is stripped therefrom. The forward edge of the lip may also 'be used as a support in tearing off the gauze. By varying the distance between the lip 31 and the forward edge of the member N3 the thickness of the coating applied to the gauze may be regulated. It is pointed out that by reason of the transverse closures'at each end of the guide, a surplus of plastic material is prevented from escaping.

In using the device the roll of .medical .gauze B is inserted in the magazine 25 and unrolled from the bottom. The upper member 1 9 of the guide ll is removed and the gauze pulled for wardly in the lower member 18 of the guide so 'as to extend from the front end thereof. The upper member !9 of the guide .is then telescoped onto the lower member until the dimples 35 engage in the indentations 34. The guide is then inserted through the slot is in the plate ll of the con tainer Ill and the bonnet 2"! placed'on the container. Before the bonnet is placed on the 'container the thumb screw 32 may be adjusted to depress the lip 24 and place the desired pressure on the gauze strip.

The cap i2 having been removed, the container is turned to an upright position and enough plastic material deposited therein so that when the container is turned back to a horizontal position, the level of the plastic material will stand well above the guide l1. Owing tothe frictional engagement of the guide l7,' in the sl'o't l6, said guide will remain in position during the filling operation. When the con-tainer has been filled the cap I2 is replaced with the guide extending through the slot l5. The device is then turned to a horizontal position. The openings 20 will permit the plastic material to pass through the gauze as well as to flow between the guide members I8 and i 9. The operator holds the container in one hand and. pulls the strip of auze A forwardly with the other hand until the desired length has been dispensed, whereupon the strip is torn off or cut across the lip 31. Any liquid plastic material suitable for making casts and splints may be employed.

The foregoing description of the invention is explanatory thereof and various changes in the :size, shapeand materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
